Description

Method and system for realizing personal number service of users integrating telephone network and IP network

technical field

The invention relates to the technical field of voice communication, in particular to a method and a system for realizing the personal number service of merging telephone network users and IP network users.

Background technique

Traditional voice communication is mainly realized through the PSTN (Public Switch Telephone Network) network, that is, the telephone (Phone) in the ordinary sense, and its network structure is shown in Figure 1.

With the development of the Internet, the use of multimedia computers (PCs) to carry out calls is gradually becoming popular. Therefore, intercommunication between PSTN users and IP network users has also become an inevitable requirement. Currently, there are two ways to integrate PSTN users and IP users:

1. PC to Phone: Enter the phone number on the PC side, and then the software on the PC side sends the call to the IP phone gateway, and the IP phone gateway initiates a call to the PSTN network, and finally the call reaches the called PSTN phone user. In this way, the conversion between the IP network and the PSTN network is completed through the IP telephone gateway.

2. ICW (Internet Call Waiting): ICW is mainly used to solve dial-up Internet users answering incoming calls while surfing the Internet. The user first needs to apply for ICW service registration at the Telecom Service Registry. When the user accesses the Internet, the user's ICW client software will register the user's phone number and the IP address of the computer used to an ICW service server. When a call comes, the call will be automatically transferred to the ICW service server according to the ICW service registered by the user, and the server will initiate a call to the pre-registered IP address through the IP telephony gateway, and the user can make a call after accepting it.

When merging PSTN users and IP users, the problem of PC to Phone is easy to solve, because you can directly input the called phone number, but the problem of Phone to PC is more difficult to solve, because PC does not have an identification, for dialing Internet users, their IP addresses are not fixed. The ICW service only partially solves the intercommunication problem between telephone users and dial-up PC users, but does not solve the intercommunication problem between telephone users and all PC users.

Both of the above two services do not provide a simple means to solve the intercommunication problem between PSTN telephone users and PC users, and also have the following problems:

A user may have multiple numbers, which are difficult to remember and manage. In particular, a user may use a phone for a period of time and a PC for a period of time, which brings trouble to the person looking for this user; Its own billing system is not convenient for unified management, and it also brings troubles to users when paying bills; when a user is on a business trip, his phone number will change, and how other users can contact him becomes a big problem. question; and so on.

Detailed ways

The present invention integrates the four services of Phone to Phone, Phone to PC, PC to Phone, and PC to PC through the personal number service. Therefore, the personal number service of the present invention can also be vividly called ONLY (One Number Link You) service. Its core is: uniformly assign a personal service number to each user, and identify the user through this number, regardless of whether the user is an IP network user or an ordinary telephone network user; through the personal number service server (ONLY Server) and the personal number user server (User Sever), complete the control of the call connection process according to the pre-customized call control strategy of the service user, and realize the intercommunication between the telephone network user and the IP network user.

Below, the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

First, please refer to the schematic diagram of the basic networking for implementing the ONLY service shown in FIG. 2 .

If the user applies for the ONLY service, he can register online through the WEB page provided by the Web Server (Web Server), or he can register online by dialing the artificial voice station, or through an agent on his behalf. The number of the ONLY service can be "access code + personal service number". The personal service number uniquely identifies the user, and a unified database is used for user management. When a user applies for registration of the ONLY service and corresponds to an ONLY number, such as "166-12345678", no matter where the user is or whether he is online or not, he can easily find the user by dialing his ONLY number.

Web Server provides users with user information registration, query, modification, and deletion through WEB pages.

PCC (PC Client) is a client software module running on a PC, which provides PC users with voice calls. Its module structure is shown in Figure 3. Among them, the message transceiver module completes the sending and receiving of Ethernet messages. When it is found to be an MGCP message, it sends the message to the MGCP protocol processing module for processing. When it is found to be a voice packet, it sends the message to the voice packet. The packet processing module completes the processing of voice packets. The call processing module completes the control and processing of calls, and at the same time controls the sound card driver module to play and record the corresponding voice packets through the sound card of the computer.

GW (Gateway) gateway completes the conversion of voice and signaling between PSTN and IP network. The GK (Gatekeeper) gatekeeper completes functions such as access control, route search, and bandwidth control, and mainly completes route analysis and query to the corresponding called GW according to the ONLY number.

IVR MS (Interactive Voice Response Media Server) interactive voice response media server, realizes the interactive voice response function on the IP network. It can receive the user's keys and voice input, and make different responses according to different applications, for example, it can complete the function of telephone banking.

VoiceMsg MS (Voice Message Media Server) voice mail media server can complete the voice mail function on the IP network.

FAX S&F (FAX Store and Forward Media Server) stores and forwards fax media server, which can receive fax data from GW or other IP terminals, and forward it in an appropriate way (such as E-mail, ordinary fax).

Resident GW (Resident Gateway) provides a direct connection to the telephone line, which can be directly connected to an ordinary telephone without the need for switches and other equipment.

The ONLY service server (ONLY Server) completes the function of call control in the IP network, which is equivalent to the switch in the PSTN network, but it is located in the IP network, and the technologies used are all related to IP. ONLY Server only handles signaling and does not handle voice media streams.

In actual application, whether it is a PSTN ordinary telephone user or a PC user, once the ONLY number of the called service user is dialed, the call will be connected to the ONLY Server first, and the ONLY Server will perform subsequent connection operations. The connection control of all business users is completed through ONLY Server, which ensures the unified management of PSTN ordinary telephone users and PC users.

ONLY Server is also responsible for interacting with User Server to complete authentication and billing.

See Figure 4, a schematic diagram of the internal modules and data flow of ONLY Server. These include:

Call Control Module (Call Control Module) - realize ONLY Server business control, call control. Including: access control; routing request; call signaling forwarding; conversion between different call protocols; transparent transmission of DTMF numbers; soft shutdown function; call capacity limit function; accept GK management and report status to GK; Notify the User Server when the user fails to initiate a call; generate original billing information; etc.

MGC adaptation module (MGCA Module)--receives the MGCP message from the following MGC command module (MGCC), and converts it into a Q931 message that the call control module can understand. The MGCA module shields the specific details of the MGCP protocol and sends it to the call control module. Provides a simple and unified interface that simplifies the handling of the call control module. Functions include access control, conversion between different call protocols, DTMF code transparent transmission, MS (Media Server) resource request and release notification, etc.

MGC Management Module (MGCM Module) - realizes the resource management and deployment of MG (IVR and VM), and is responsible for the registration of MG. Including: MG registration; MG status maintenance; MG resource management; call resource allocation;

User Client Module (User Client Module)--realize the communication between ONLY Server and UserServer. Including: log in to User Server when ONLY Server starts; log off from User Server when ONLY Server stops running; use heartbeat message to maintain TCP connection between ONLY Server and User Server; call query; notify User Server when call fails; send billing information; etc.

Config Manage Module - maintains configuration variables, writes user logs, system logs, and debug logs. Including: maintaining configuration variables; writing user logs; writing system logs; writing debugging logs; writing bill logs; writing statistical information; etc.

MGC command module (MGCC Module) - realizes the conversion between the upper layer message and the MGCP protocol. Including: codec; UDP datagram timeout retransmission; function of sending at most once; association of MGC command and response; etc.

H.323 protocol stack processing module--receive H.323 protocol message from the network port, process the message and send it to the call control module; receive the processing request of the call control module, convert it into an H.323 protocol message and send it out; wait.

Fig. 5 shows the interactive relationship between the above modules.

ONLY Server completes the conversion between H.323, SIP and MGCP protocols. H.323 protocol is generally adopted between ONLY Server and GW, and SIP or MGCP protocol.

Referring to shown in Figure 6, it is a schematic diagram of the system structure of the ONLY user server (User Server). Functionally, User Server includes two parts: the processing of ONLY Server messages and the processing of PCC messages. User Server interacts with PCC to complete the registration, query, modification and deletion of user information. User Server interacts with ONLY Server to complete authentication and accounting functions. At the same time, the user-customized call control strategy is stored in the database. When a call comes, ONLY Server inquires from UserServer to obtain the user's pre-customized calling method. If the call is to an ordinary phone or a mobile phone, the ONLY Server initiates a call to the IP telephone gateway of the called location; if the call is to a PC client, the ONLY Server directly initiates a call to the called client; if a message is required, the ONLY Server sends the Calls are diverted to voicemail. The database of User Server can be realized by the catalog server (Index Server) that sets separately, and Index Server is a database system, finishes the preservation of user information and the preservation of call policy.

When the ONLY Server interacts with the User Server, the state transition of each ONLY business user is shown in Figure 7. When the user registers, the idle state is transferred to the registered state, and when the user logs out, it returns to the idle state; when the billing request is received When it enters the billing state, it returns to the registration state after sending the billing response; it enters the calling state when it receives a call request, and returns to the registration state after sending the call response.

In the ONLY system shown in Figure 2, the ONLY Server is responsible for controlling the connection. All calls to the ONLY number will be routed to the ONLY Server. The ONLY Server sends a request to the UserServer. The status and registration data obtain the actual phone number or IP address that should be connected, and return it to ONLY Server, and ONLY Server initiates a call to this phone number or IP address. User Server can also return multiple phone numbers or IP addresses. At this time, ONLY Server will sequentially connect these numbers in case of connection failure.

As shown in Figure 8, when the ONLY service is applied in multiple cities, a set of GW, ONLY Server, User Server, and IVR MS can be set in each city, and one or more of these components can be configured according to the number of users. GK completes the routing function of the entire system, so one is set up centrally. Database systems such as Index Server and User Server can be placed centrally as shown in Figure 6, or a distributed database system can be used to store part of the data in each city, depending on the specific situation.

When realizing the ONLY service provided by the present invention, each user can register an own number, that is, the ONLY number. This number is used to uniquely identify the user. When registering, the user can register his office phone, home phone, mobile phone, pager and other contact information according to his needs, and pre-customize the call control strategy. The way of user registration can be online registration or telephone registration.

Others can directly input the ONLY number of the called user on the ordinary phone or PC client software, and the ONLY system will query the location and current status of the called user according to the user information. The status includes the current time and the called user Whether to surf the Internet. Then proceed according to the predetermined control strategy. For example, when the user is online, the ONLY system will directly transfer the call to the user's PC client software; when the user is not online, call the office phone or mobile phone according to the contact information registered by the user; if there is no other contact information and If the user has a voice mailbox, the call will be transferred to the voice mailbox.

In the ONLY service provided by the present invention, the calling user can be a PC user or a telephone user, and what they obtain is the same service; the called user may be a PC user or a telephone user, which depends on the user's current to determine the usage status and registration data. In this way, through an ONLY number, PC users and telephone users are integrated, and four services of Phone to Phone, Phone to PC, PC to Phone, and PC to PC are realized at the same time.

Taking the calling party as a telephone user as an example, the main steps to implement call connection are as follows:

1. The gateway receives the call from the calling user, queries the GK, obtains the information of the ONLY Server, and sends the call information to the ONLY Server through the IP network. The call information includes the calling and called numbers, the signaling transmission address of the calling party, and the like.

2. The IPN Server sends the obtained calling and called numbers to the User Server to query the called information. In the User Server or in the Index Server connected to the User Server, there are stored call control strategies prepared by the user; Policy list; User Server uses the personal service number passed by ONLYServer as an index to obtain the current call policy list, and transmits it to ONLY Server through the IP network.

3. The ONLY Server receives the call strategy list and analyzes the call strategy list; in the call strategy list, the call control strategy previously formulated by the called service user is stored, and it corresponds to the information of multiple call terminals to choose from. Different terminals correspond to different service type signs and corresponding terminal information, such as PC terminal information such as calling IP address and port number; ONLYServer performs call connection according to the call control strategy formulated in the service list.

4. Depending on the service type, the process of initiating a call is also different. For example, when initiating a call to a PC, since the IP address and port number of the PC have been included in the call policy list, at this time, ONLYServer directly initiates a call to the PC; and If the called is a Phone, the ONLY Server will first query the GK to obtain the IP address and port number of the called gateway, and then initiate a call; if the called is an IVR or other media server, the ONLY Server needs to go through a specific channel Obtain the resource information of the media gateway, and then initiate a call.

5. If a call is unsuccessful, ONLY Server will initiate a call again according to the next entry in the call policy list; the order of call transfer is consistent with the order of call policy list items, and the call will be transferred to the corresponding terminal in turn until the call is accepted until, or until the last call policy list item.

In the following, a typical call flow of the ONLY service of the present invention will be described with reference to FIGS. 9-12 respectively.

Refer to Figure 9 and Figure 10, which are typical ONLY service PC-to-PC and PC-to-PC call flows transferred to Phone respectively.

The PC user enters the called ONLY service number to initiate a call request to the ONLY Server.

ONLY Server receives the call, sends a call request message to User Server, and sends the ONLY service number to User Server for number change.

User Server responds to the call response message, and returns the call list corresponding to the ONLY call number according to the user's pre-customized call control strategy.

ONLY Server initiates a call to the PC client. When the call is transferred to the Phone, a route analysis command is sent to the GK, and the GK returns the address of the called gateway after the route analysis, and then initiates a call to the called gateway.

Refer to Fig. 11 and Fig. 12, which are the call flow of typical ONLY service Phone to PC and Phone to PC and then to Phone.

The PSTN user dials the ONLY number of the called ONLY service user, and the exchange connects the call to the GW according to its preset route after receiving the call.

GW receives this call, and sends the ONLY service number to GK to request for routing analysis.

GK returns the IP address of the ONLY Server in the route analysis result.

GW initiates a call to ONLY Server.

ONLY Server receives the call, sends a call request message to User Server, and sends the ONLY service number to User Server for number change.

User Server responds to the call response message, and returns the call list corresponding to the ONLY call number according to the user's pre-customized call control strategy.

ONLY Server initiates a call to the PC client. When the call is transferred to the Phone, a route analysis command is sent to the GK, and the GK returns the address of the called gateway after the route analysis, and then initiates a call to the called gateway.

The effect of the method of the present invention is: the user only needs to have an ONLY number, no matter whether the user is a PC user or a telephone user, and no matter whether the user is surfing the Internet or working at work, other people can find him conveniently only by remembering the number. The invention solves the problems of number, billing, mapping of multiple numbers and user movement when PC users communicate with ordinary phone users.

The realization of the ONLY service has nothing to do with the specific network environment, and can be realized under different networks.
